UNITED STATES PATENT OFFICE \VALTER STILES, OF BLOOMFIELD, IOWA.

IMPROVEMENT IN C3AIR-COUPLINGS.

Specification forming part of Letters Patent No. 147,350, dated Fehuary10,1574; application fihd September 20, 1873.

To all whom it may concern Be it known that I, WALTER STILES, ofBloomfield in the county of Davis and State of Iowa, have invented a newand Improved (far-Coupling, of which the following is a specification Myinvention consists of an elbow-shaped barorframe, arranged on the d ra-uhead so as to holdup the coupling-pin above the link; also holdthelinkup level, or alittleinclined, so as to enter the drawhead of anapproaching ear and also so that when the two cars come together the twoframes will push each other for ward at the top, so as to release thecouplingpins, and let them fall through the link, and couple the carsselt actingl v.

Figure l is a longitudinal sectional elevation of a couple of drawheadsconstructed accord ing to my invention. Fig. 2 is a front elevation ofone of the draw-heads, and section of the link, on the line :1- ;r ofFig. 1.

Similar letters of reference indicate corresponding parts.

The pin A is suspended from an arm B, which projects from the verticalrod 0, sliding up and down in supports on the end of the car, and havingthe rod l) extending down into a groove, 16, in the block F above thedrawhead. The lower end of this bar is widened a little, and inclined atG, to force the upper end of the elbow bar or frame H forward, and riseabove it when the pin is to be pulled out, and then rest-011 the top ofsaid frame. This frame is pivoted to the drmv-head at l, and has springsK; or it may be cords and weights, which pull the top back under foot Gas soon as rod 1) has been raised high enough to lift the pin out of thelink, and hold said pin read v to let it fall when required. Below thedrawhead the frame H supports a plate, J, which rises a little above thebottom wall of thehole for the link in the draw-head, when the pin isheld up, and holds the outer end of the link up so as to enter thedraw-head ot' the other car.

\Vhen the two bars J of the ears bein coupled strike together, the upperends of the frames H are thrown forward, out from under therods l), andlet the pins fall, and thus couple the cars self-aetingly.

I propose to have the rods 0 extend to the top of the car, so that thehrakeman can liftup the pin, and adjust the coupling while on the top ofa freight-car.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- The combination of the elbow-flame H J arm B, rods 0and I), and spring K with the draw-head and coupling link and pin,substantially as specified.
